Help, my Samsung Galaxy S II has boot loop issue after I installed custom firmware!!! Err… This is the first time that I faced boot loop issue on my Samsung Galaxy S2. Yes, right after I factory data reset the newly installed Lite’ning ROM v5.0. Seem like Lite’ning ROM v5.0 can’t survive factory data reset from phone and I tried to wipe data/factory reset and wipe cache partition with ClockworkMod Recovery also did not help. Reinstall Lite’ning ROM through Odin again also does not help to solve boot loop issue. No worry, here is the step by step guide to solve boot loop issue on Samsung Galaxy S2.
